D365 Online CRM Load Testing

Hi All,

We are trying to load test our CRM application using the IE recorder as well as Fiddler recorder as web tests. But we are facing lot of Unauthorized access errors for lot of requests recorded under the webtest through both channels. We are getting these errors just after webtest is recorded so it shouldn't be the access token issues but still open for suggestions.

Example: - https://<org>.crm.dynamics.com/AppWebServices/MessageBar.asmx

We get unauthorized error on this request.
